Charlottesville Region Broadband Availability
Lee LeBoeuf
7/30/2021
Data Source
- These data come from the FCC's data on broadband availability.
- FCC data is released biannually on a year and half delay from when it was collected. New data can be downloaded from this link.
- Data presented here are from June of 2020.
Data specifics
- All internet providers must submit form 477 to the FCC biannually detailing the Maximum download and upload speeds (Mbps) they advertise to consumers along with other information about the company.
- The FCC makes these data publicly available on a year and a half delay from when all 477 forms are submitted.
- Limitations: (1) The data are available at the census block level, but are likely to overstate coverage because if an internet provider provides internet to a single person in a census block, the entire census block is marked as having coverage by that provider.
- Strengths: (1) These are the same data used by the government to make policy decisions regarding broadband access. (2) Trump signed an act into law in March of 2020 that is supposed to improve the limitation listed above.
